Well I screwed up, I got 2 rolls of # 14 wire from my boss. I check the one roll just to see how many strands it had & put the rolls on a pole chucked the other end in a drill & twisted them up. That really work great perfect twist. So I ran the wires thru the boat & even thru some tubing with some work but I got it. So I put the floor & seat & side panels all back in. And started to do my soldering & then I discovered the wire I didn't check was solid. One of the dumbest things I ever did. I should have realized how stiff it was & the way I managed to get it thru that tubing. Well anyway is it alright to use the solid wire I'm going to use it for the negitive side ? I checked the voltage & its the same on both ends.
